Problems solved by technology

When the temperature of the working environment is high, the thin film transistor will have reverse leakage after being heated. If the polarity conversion mode of the thin film transistor liquid crystal display is column inversion at this time, the display will appear relatively poor display. question
Therefore, in the above cases, the column inversion method cannot adapt to and meet the requirements of the changing working environment, and the flexibility is poor

Abstract

The invention discloses a display screen polarity inversion method and a display screen polarity inversion device. The method comprises the following steps: acquiring the current temperature value of a terminal display screen; determining the current polarity inversion mode of the display screen; determining that whether the display screen satisfies the preset conditions or not based on the current temperature value and the current polarity inversion mode of the display screen; and if the display screen satisfies the preset conditions, calling an inversion instruction corresponding to the preset conditions, and adjusting the current polarity inversion mode of the display screen according to the inversion instruction. Compared with the prior art, the method and the device have the advantages that according to the preset conditions satisfied by the terminal display screen, the inversion instruction corresponding to the preset conditions can be called for adjusting the polarity inversion mode of the terminal display screen, so that the terminal display screen can be switched to different polarity inversion modes under the different conditions, and therefore, the flexibility of the polarity inversion modes of the terminal display screen is improved.

Description

technical field [0001] The invention belongs to the technical field of display screens, in particular to a method and device for polarity conversion of a display screen. Background technique [0002] In a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short), the driving voltage of the liquid crystal molecules cannot be fixed at a certain value for a long time, otherwise the liquid crystal molecules will be polarized, causing them to gradually lose their optical properties. Therefore, the driving voltage of the liquid crystal molecules needs to be polarized. Common polarity transformation methods include frame inversion, line inversion, column inversion, and dot inversion. [0003] In actual production applications, the commonly used polarity conversion methods are column inversion or dot inversion. However, during the use of thin film transistor liquid crystal display screens, with the use of the display screen for a long time and different use scenarios, its wo...
